Know More About This Test

Random blood sugar measures glucose levels at any time of day, regardless of meals. It is a quick screening tool for diabetes and hyperglycemia. Although convenient, it is interpreted along with symptoms and other glucose tests.

Why Is This Test Recommended?

Random blood sugar testing is recommended to screen for diabetes, evaluate symptoms like excess thirst, frequent urination, or fatigue, monitor uncontrolled diabetes, and provide emergency assessment of blood sugar status.

What Do the Results Indicate?

Normal levels are <140 mg/dL. High levels are ≥200 mg/dL. A value above 200 mg/dL with symptoms suggests diabetes. If abnormal, fasting glucose or HbA1c testing may be needed for confirmation.

How Is the Test Performed and Prepared For?

Blood sample is collected. No preparation is required.

Frequently Asked Questions (FAQs)

1. Is fasting required?
   No; random blood sugar is performed at any time without fasting, making it convenient for quick screening.

2. Can it diagnose diabetes alone?
   No; while suggestive when ≥200 mg/dL with symptoms, diabetes diagnosis requires confirmation with fasting glucose or HbA1c testing.

3. Is it reliable?
   Yes for screening; it provides a quick snapshot of current glucose levels, though it's less precise than fasting tests.

4. Does stress affect it?
   Yes; physical or emotional stress can temporarily raise blood sugar levels by triggering hormones like cortisol and adrenaline.

5. Can results vary daily?
   Yes; random blood sugar fluctuates based on recent meals, physical activity, stress, illness, and time of day.

6. Is it used in emergencies?
   Yes; random blood sugar is commonly used in emergency settings to quickly assess hyperglycemia or hypoglycemia requiring immediate intervention.
